P0010

Message

Feature requires IEC 61131-3:2013 (use –dialect iec61131-3-ed3)

This error occurs when an IEC 61131-3:2013 feature is used without enabling the 2013 standard.

Example

The following code will generate error P0010:

PROGRAM main
VAR
    duration : LTIME;
END_VAR
END_PROGRAM

The code uses LTIME, which is an IEC 61131-3:2013 data type and is not available in the default mode.

To fix this error, enable IEC 61131-3:2013 support:

  • CLI: Pass the --dialect option:

    ironplcc check --dialect iec61131-3-ed3 myprogram.st

  • VS Code: Set ironplc.dialect to iec61131-3-ed3 in your extension settings. See Settings Reference for details.

See Enabling Dialects and Features for more about standard editions.

Think IronPLC is wrong about this?
